Abstract
The utility model provides a balanced extension ladder. This balanced extension ladder include a plurality of can tensile extension means, the outside also is that cup jointed the rotary sleeve on the thickest its flexible bracing piece of extension means or the fixed groove that leads to is opened to flexible bracing piece bottom, through on the rotary sleeve or lead to the inslot and be fixed with the balancing pole, make the balancing pole position can take place to rotate, two balancing poles are in between the two flexible bracing pieces when extension ladder does not use like this, then open two flexible bracing pieces when using, carry convenience comparatively, and the balancing pole is when the level, and it is fixed by the mounting.
Description
Technical field
This utility model belongs to ladder field, specifically, is a kind of gimbal lever balance extension ladder easy to use.
Background technology
Ladder is a kind of common instrument of climbing to a higher point, and in order to easy to carry, existing ladder is typically all processed into extension ladder, and
So, due to not having bascule, easily rollover phenomenon when using on irregular ground, therefore goes out on market in existing extension ladder
Show the balance extension ladder installing the gimbal lever additional, but this kind of extension ladder has been that a straight-bar is fixed on ladder base, and straight-bar has prolonged
Stretch out ladder, this causes inconvenient to carry again.
Utility model content
In view of the defect existing for existing balance extension ladder, technical problem to be solved in the utility model is: provides one
Plant balance extension ladder easy to carry.
To achieve these goals, according to one side of the present utility model, there is provided a kind of balance extension ladder, comprising:
Ladder, ladder is socketed to form by multiple hollow telescopic units, and each hollow unit is again by two telescopic supporting rods be connected to two and stretch
The cross bar composition of contracting support bar, by stretching or promoting less telescopic unit to pull up ladder height, by stretching in outermost
All it is fixed with its two telescopic supporting rod of unit and can be fixed with support outside the gimbal lever around the gimbal lever of telescopic supporting rod rotation
Foot, makes can fix during gimbal lever's level.
Further, a kind of preferred as gimbal lever's rotation, the described gimbal lever is stretched with described outermost telescopic unit
It is provided with rotary sleeve, described rotary sleeve is socketed on described telescopic supporting rod, and is provided with telescopic supporting rod between contracting support bar
Spacing collar prevents from moving on rotary sleeve, so that the gimbal lever can be rotated around telescopic supporting rod by the drive of rotary sleeve, and by flexible
The horizontal both sides of support bar set spring action buttons, and spring action buttons can eject rotary sleeve, make can fix during gimbal lever's level.
Further, as another kind of preferred, its retractable support masthead of described outermost telescopic unit of gimbal lever's rotation
Portion has clamping groove, and gimbal lever's activity is connected in clamping groove, so that the gimbal lever can be rotated along groove two open side, described
When it rotates to horizontal level, it passes through buckle clamping and telescopic supporting rod between for the gimbal lever.
Application the technical solution of the utility model, by the rotatable characteristic of the gimbal lever, when making balance extension ladder not use
The gimbal lever can be between two support bars, and can fix, and carrying can be very convenient.
Brief description
The accompanying drawing constituting this utility model part is used for providing further understanding to of the present utility model, this utility model
Schematic description and description be used for explaining this utility model, do not constitute to improper restriction of the present utility model.Attached
In figure:
Fig. 1 is existing balance extension ladder telescopic supporting rod structural representation.
Fig. 2 is that the gimbal lever described in the utility model one of which fixes schematic diagram.
Fig. 3 is another kind of fixing schematic diagram of the gimbal lever described in the utility model.
Reference: 1, telescopic unit；2nd, telescopic supporting rod；3rd, cross bar；4th, rotary sleeve；31st, the gimbal lever；41st, support feet；

Specific embodiment
To describe this utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case of prominent, the embodiment in the application and the feature in embodiment can be mutually combined.
Fig. 1 is the telescopic supporting rod 2 that existing balance extension ladder outermost is also telescopic unit the thickest, and from figure, we can
To find out, two telescopic supporting rod 2 bottom is fixed with the gimbal lever 31 exceeding two telescopic supporting rods 2, and the gimbal lever 31 both sides are each solid
Surely there is a support feet 41, though such design can effectively prevent the side plate of ladder, inconvenience more when carrying, such as electromobile
Or motorcycle or bicycle carry particularly obvious.
The balance extension ladder one of which structure that Fig. 2 provides for this utility model, it comprises ladder, and ladder is by multiple by big
Form to little telescopic unit 1, and less telescopic unit 1 can be pulled up, from figure it will be seen that above-mentioned stretch
Unit 1 by two telescopic supporting rods 2 and connects the cross bar 3 of two telescopic supporting rods 2 and forms, namely thick two flexible of outermost
One rotary sleeve 4 is respectively socketed with strut 2, rotary sleeve 4 is fixed with the gimbal lever 31, outside the gimbal lever 31, is fixed with support feet 41,
Can be rotated by the position that the drive of rotary sleeve 4 makes the gimbal lever 31, so when extension ladder does not use at the Shi Liang gimbal lever 31
Between two telescopic supporting rods 2, perfection solves existing balance the problems of extension ladder so as to easy to carry.
Of course herein it should be noted that, above-mentioned rotary sleeve 4 is preferably fitted close with telescopic supporting rod 2, and flexible
The spacing collar 51 moving on fixing restricted rotary sleeve 4 is needed on strut 2.
The balance extension ladder another kind structure that Fig. 3 provides for this utility model, it eliminates rotation on the basis of Fig. 2
Set 4, is changed to open fixing groove in outermost two telescopic supporting rod 2 bottom, the gimbal lever 31 is fixed on groove by fixing bolt 57
Interior, such gimbal lever 31 just vertically can have rotated along groove.
Finally also need to explanation a bit, need during the above-mentioned gimbal lever's 31 level to fix, therefore flexible in the structure of Fig. 2
2 liang of levels of strut are surveyed and are needed to be fixed with spring action buttons, and need opened hole on rotary sleeve 4, by the cooperation of spring action buttons and through hole
The gimbal lever 31 level is made to fix, in the structure of Fig. 3, the horizontal both sides of telescopic supporting rod 2 are required for fixing button, when the gimbal lever 31 water
Clasp thereon can buckle in button and fix at ordinary times.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, the present invention can have various changes and change.All of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
